I just had a look at the new toolset. First a thing about
it's name. The
compiler is named cxx, the platform is Tru64, so shouldn't
the toolset be
named cxx-tru64 or tru64-cxx or something similar?
The simple example seems to work:
> bjam -a -d+2 tru64
tru64.compile.c++ bin/tru64/debug/hello.o
cxx -c -std strict_ansi -nopure_cname
-noimplicit_include
-timplicit_local -ptr
"bin/tru64/debug/cxx_repository"
-msg_display_number
-msg_disable 186,450,1115 -D__CNAME_OVERLOADS -g3 -O0
-inline none -o
"bin/tru64/debug/hello.o" "hello.cpp"
But I'm missing -gall, and -model ansi on the compiler
command line.
Looking at the jam file, the model feature has been disabled
explicitly.
Here is an excerpt from the compiler man page about this
feature:
<quote>
-model [ansi | arm]
[Tru64] Determines the layout of C++ classes, name mangling,
and
exception handling. On Tru64 UNIX, the default is -model
arm; on
Linux Alpha, the default is -model ansi. The -model arm
option is not
supported on Linux Alpha.
The -model arm option is the default and generates objects
that are
link compatible with all HP C++ releases prior to Version
6.3, and
with all objects compiled using the -model arm option in HP
C++ Ver-
sion 6.3 or later. Specifying this option defines the macro
__MODEL_ARM.
The -model ansi option supports the complete ISO/ANSI C++
specifica-
tion, including distinct name mangling for templates. The
ANSI model
also reduces the size of C++ non-POD class objects. Note
that this
option generates objects that are not compatible with prior
releases
of HP C++, or with objects compiled using the -model arm
option.
If you specify the -model ansi option, you must recompile
your entire
application, including libraries. Specifying this option
defines the
macro __MODEL_ANSI.

tru64.link bin/tru64/debug/hello
cxx -noimplicit_include -g -o
"bin/tru64/debug/hello"
"bin/tru64/debug/hello.o" -lrt -lm
Here the model flag is missing as well.
The next example fails:
> bjam -a -d+2 tru64

cxx -c -std strict_ansi -nopure_cname

I have no idea where the -qrtti flag comes from in the
original V1 toolset,
but it seems that the corresponding rule is never used
because building
shared libs works on Tru64 in V1. So using the regular link
rule should
instead should work, I guess.
About the C compiler, I don't think there are any flags that
will help you
here. You have to invoke cc and not cxx, as is the case in
the V1 toolset.
I don't have time for more right now, but I will try to
address the other
FIXME comments in the toolset file this week.
